What is glutathione?
Before reading any glutathione injection dosage chart, it helps to know what is in the vial. Glutathione is a tripeptide, a chain of just three amino acids: glutamate, cysteine and glycine, with the glutamate linked through its side chain rather than in the usual way. The body makes it naturally, and it is one of the most studied antioxidant molecules in cell biology. You will see it labeled as GSH, reduced glutathione or L-glutathione.
Because it is so small, vendors often group glutathione with peptides, and “glutathione peptide dosage” is a common search. It is also sold widely as an oral supplement and in skincare. This page is only about vials of powder that are reconstituted with liquid; the calculator does not apply to capsules, tablets or creams. It describes the math, not any effect in the body.
How much BAC water for a glutathione vial?
Glutathione vials are measured in hundreds of milligrams, so the numbers look very different from a typical peptide vial. The most common research sizes are 600 mg and 1500 mg. With that much material, even a large volume of water produces a strong solution, and mcg per unit runs into the hundreds or thousands. The chart below shows mcg per unit for both sizes across several water volumes.
| BAC water | 600 mg vial | 1,500 mg vial |
|---|---|---|
| 3 mL | 2,000 mcg/unit 200 mg/mL | 5,000 mcg/unit 500 mg/mL |
| 5 mL | 1,200 mcg/unit 120 mg/mL | 3,000 mcg/unit 300 mg/mL |
| 10 mL | 600 mcg/unit 60 mg/mL | 1,500 mcg/unit 150 mg/mL |
Each cell shows mcg per unit on a U-100 syringe (100 units = 1 mL) and the resulting concentration.
Two practical limits matter more here than with small vials. First, the volume you add has to fit in the vial, so check its actual capacity on the label before planning a large volume. Second, a U-100 syringe holds at most 100 units, which is 1 mL, so at lower concentrations the amount you have may need more liquid than one syringe holds. Keeping everything in milligrams makes these large numbers easier to check, since 1 mg is 1,000 mcg and a slip between the two is easy to miss. The mg to mcg conversion guide covers the switch.
Worked example: glutathione 600mg reconstitution
For example, if the amount you already have is 100 mg and a 600 mg vial is mixed with 6 mL of BAC water:
The math: 600 mg ÷ 6 mL = 100 mg/mL (100,000 mcg/mL), which is 1,000 mcg per unit. 100 mg ÷ 100,000 mcg/mL = 1 mL = 100 units on a U-100 syringe.
The concentration is the vial amount divided by the water volume, the volume is the amount divided by that concentration, and units are mL multiplied by 100. With vials this large, always check whether the result fits within the capacity of the syringe you are reading.
Glutathione 1500mg reconstitution
The same steps apply to the bigger vial. For example, if the amount you already have is 75 mg and a 1500 mg vial is mixed with 10 mL:
The math: 1,500 mg ÷ 10 mL = 150 mg/mL (150,000 mcg/mL), which is 1,500 mcg per unit. 75 mg ÷ 150,000 mcg/mL = 0.5 mL = 50 units on a U-100 syringe.
Whichever vial you have, enter amounts in the unit printed on your own paperwork and let the glutathione reconstitution calculator do the conversion. A mix-up between mg and mcg on a vial this size produces a result that is off by a factor of a thousand.
Glutathione injection dosage chart: what the numbers mean
A glutathione injection dosage chart on this site is a conversion table. Each cell tells you how many micrograms sit in one unit of liquid for a given vial and water volume. It does not tell you how much glutathione to use, how often, or by what route, and nothing here should be read that way. The only amount in the calculation is the one you type in.
If you are comparing numbers from a label or a professional’s instructions, use the calculator to translate them into mL and units, then check that the result is realistic: a fraction of a unit or several full syringes usually signals a unit error or a typo in the vial size. The BAC water for peptides calculator on the homepage uses the same formula if you need to work with a different vial size.
Glutathione reconstitution notes from supplier labeling
Glutathione dissolves readily in water, and research suppliers list bacteriostatic water or sterile water as the diluent. Some suppliers specify storing the powder cold and protected from light, and some note that the reconstituted solution should be refrigerated and used within a set period, because glutathione in solution can oxidize over time. Some labels also mention a mild sulfur odor, which comes from the cysteine in the molecule. These are points from product labeling, not directions from this site; follow the label and a qualified professional.
If a large vial will be drawn from many times, the diluent’s own limits also apply. A punctured multi-dose vial of BAC water should be dated and discarded within 28 days unless the manufacturer states otherwise, so the BAC water vial size you buy should match how much you actually need.
Regulatory status of glutathione vials
Glutathione occurs naturally in food and in the body, but research-labeled vials of powder sold online are not FDA-approved drug products, and a clean calculation cannot confirm their identity, purity, sterility or suitability for any use. Other compound-labeled calculators appear in the peptide library.
Glutathione FAQ
How much BAC water for a 600 mg glutathione vial?
The water volume only sets the concentration, so there is no single required amount. The chart shows mcg per unit for several volumes; check the vial’s capacity and the product labeling before choosing one.
Is this a glutathione injection dosage chart?
It is a conversion chart. It shows how much glutathione is in each syringe unit for a given vial and water volume and converts an amount you already have into units. It does not recommend a dose.
Why are the numbers so large for glutathione?
Glutathione vials hold hundreds of milligrams instead of a few, so every unit of liquid carries far more material than with a typical peptide vial. Working in mg rather than mcg keeps the figures easier to read.
Does the calculator work for glutathione capsules?
No. It only applies to powder in a vial that is reconstituted with a measured volume of liquid.
Is glutathione a peptide?
It is a tripeptide made of glutamate, cysteine and glycine, which is why vendors often list it with peptides, although it is much smaller than most of them.
